A description is given of a concrete-protecting panel with integrated undercut protuberances which has an enhanced resistance to groundwater pressure. The protuberances or wing-element pairs (3) of the plastic panel (1) have spread wing elements (3) which may spread open even further in their top region 3.1. The wing elements 3 are connected to one another by a supporting web 4, of which the height is at least 70% of one wing-element pair. The wing-element pairs 2 are fastened on the base plate 5 of the protuberance- containing panel 1 via a foot widened in an arcuate manner. |
